HOOP-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,243, datedSeptember 14, 1886.

Application filed March 25, 1886. Serial No. 196,486. (No model.)

To all whom it may concern:

Be'it known that I, ALEIYANDER F. XVARD, of Detroit, in the county of\Vayne and State of Michigan, have inventednew and useful Improvementsin Hoop-Ooilers; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings,whieh form my machine is shown in the improvedform hereinafter described, Figure 1 is a perspective view of themachine, looking toward the rear and one side thereof. Fig. 2 is a frontelevation thereof. Fig. 3 is a horizontal central section on the axis ofthe coilinghead. Fig. 4 is a vertical cross-section on the line a: a inFig. 6. Fig. 5 is a plan of the oscillating counter carrying thefrictionmlleys and driver. Fig. 6 is a horizontal section of the machine, similar to Fig. 3,with the parts carried by the main shaft shownin plan, however,- instead. Fig. 7 is a detached elevation of thecoiling-head. Fig. 8 is a detached perspective view of the, hinged gate.

A is the frame of the machine, provided with suitable legs, and formingin front of the machine a circular opening, to which is secured thecircular face-plate B, which is also provided with a circular opening,in the center of which is journ'aled in suitable bearings in the framethe main shait C. To the front end of this shaft is secured thecoiling-head D, provided with the circular rim a, projecting about thewidth from the face-plate, and upon which the hoops are coiled. A11opening, b, is cut into the coiling-rim, and a polished piece of brassor other bright metal, 0, is preferably secured at one side thereof,forming part of the rim, wit-h the object of making the opening intherim more plain to the. eye when the coiler-hea-d revolves. \Vithinthe coilerhead is secured the holding-dog (Z, arranged to nip the end ofa hoop inserted through the opening I), and this dog has a tail-extensirwhich projects rearwardl y and inwardl as to interfere with the bevelededge f 01 hub 9 when the latter is projected, flit compelling the dog torelease its hold. hub g is carried by the endwise-sliding ,011 which inturn is carried by the cross-ba l which it is bolted. The ends of thecroli, F form bearings, in which the sliding 1t(l' are adj ustablysecured bymeans of set-s II. The sliding bolts Gare supported inlt, ings'l 011 the frame, which permit the bol slide freely endwise.. -A gate,K, is hinged? one end to one of the sliding bolts, and at t opposite endit is secured to the other bolt means ofa spring-latch, m, which permit.door to be opened and closed at will.

To the outer face of the door is securnail-box j, provided with adivision-.w. which forms aseparate receptacle for th of the hammer andprevents the handle hammer from dropping onto thena'ils Z otherreceptacle, in which the nails are 02 By this means the frequentspilling of 11:. the dropping of the hammer onto the na prevented.

Underneath the cross head F is 'sui journaled the rock-shaft H, har'ingroe."

I which are actuated by means of a we foot-lever, J arranged underneathand s1 connected therewith. These rock ar also connected by means oflinks lw ends of the cross-bar F, all so arranged depressing thefoot-lever J the whole formed by the sliding bolts G, cross-1n ram E,and door Kis pushed a certain 6 toward the front. This movement pusannular head f of the rain through an 1 opening between the faceplateand thehead, and also forces the (log 6 to role; hold byits impingementwith the bevele fof the hub g. The latter does not sli' the main shaft,but is provided with a ciently large bore to keep out of any fri contacttherewith. This arrangement all the weight of the sliding parts ascribed upon the sliding bolts, and t'. if the main shaft is slightlythrown om by the wearing away of thebearings w other causes, no internalfriction or hi1 the partsean occur.

L is the tension-strap, which bears against 3 loop 'in coiling. Itconsists of a steel band cwidth of the hoop, and is secured pivotallyone end to the link I; and at its other end to end of the rock-arm a.The rock-arm a, rich has a hand-lever, 11, secured to it, actuzs the camK to lift, by means ot'a chain or pe, 0, the weight 1), which restsnormally up: the floor, and is hinged atp to the l'ramcot s machine.

"I is a friction-wheel secured upon the main ft, and N is acounter-shaft journaled above a swingingboxes'q,and carryingthelrictionions M M and the drive-pulley O. The aging boxes (1 aresecured to a rock-shaft, journaled upon a bolt passing through the no. Aconnecting rod, 1-, provided with ans for adjusting its length, connectsone of swinging boxes q with a foot-lever, 1?, and adjustabletension-spring, s, acting upon the nfecting-rod r, normally keeps thefrictioneel M out of contact with the friction-wheel except when thefoot-lever P is forciblyde- :ssed. R is ahand-lever secured uponarock-shal't, :0 which is also secured a rock-arm carrying smallfriction-pinion, M, which, by means the lever B, can be thrown in andout of ontact with the friction-pinion M. A strap, secured to the end ofa rock-arm, T, hangs vnward between the friction -pinions M all soarranged that when the lever B is )ly' depressed by the operator thestrap nipped between the friction-wheels M id forcibly drawn down, and,by means connect-ion, rocks the cam K, thereby ing up on the chain 0 andlifting the it 12. the front face. of theframe of the mae, and near theouter edge of the face-plate secured the curved guide flange Q, whichBtIS about the width of a hoop over the am, and has secured to it anoverhang- }ngc, Q, all so arranged that at a certain in the operation ofcoiling the tensions caught under the overhanging flange 1 cannot bedisplaced in pushing oil the s a lever pivotally secured to the front ofthe frame. Its free inner end termiin a finger, which, by means of thefoot- ,1 and suitable con neetion therewith, n'orcibl-y depressed uponthe end of the .sOil tohold that end firmly down on the J secure it bynailin is a curved rail secured to the front side :machine underneaththe coiling-head, it the coil of hoops when pushed oil? the g-head willdrop onto it, and receive an impetus which willset it to rollry from themachine. notice, the machine being constructed ranged as described, theoperator sets tug-head to revolving by placi nghis foot lever P, thenthrusting one end of a rough the opening 11, gets it nipped by ,1. whenimmediately the coiling-head willcoil it around its rim, while theoperator quicklyinserts the 'usual number of other hoops one afteranother into the open end of the.coil. lVhilc the hoops are thus coiledthe tension-strap bears against the outer face ol' the coil with thetension produced by the weightp, which, as the coil enlarges, isgradually lil'ted higher, butihe tension produced by it is graduallydiminishing, owing to-thc decreasing leverage of the cam K. Thus thetension is kept adequate to the requirements, diminishing as the coilincreases in use, instead ol'being uniform during the whole operation,and by this means considerable power is saved. Upon the sides the coilis confined between the face-plate l) and the inner face of the gate,which latter has slight rounding projections formed thereon to reducethe friction, which is principally against the face. If the spacebetween these parts has to be increased for wider hoops,the necessaryadjustmentis ob tained by means of the setscrews 71, which permit ot'n-ojecting the bolts G any distance to form therequired clearancebetween the-faceplate and gate. As soon as the coil is formed theoperator takes his foot off the lever P and places it on thelever V,thereby pressing down 'the free end of the last hoop, which is thennailed down, after which the operator, taking hold of the hand-lever Rand depressing it,.releases the coil from the tension-strap, being aidedthereby by the curved flange Q, against which the tension-strap is held,and by placing his foot now on the foot-lever J he actuates the ram topushotf the coil, which drops on the curved rail and rolls away. Thetension-strap is prevented from being displacedby the overhanging flangewhich engages it.

Instead of releasing the tension-strap by means of the lever It, whichrequires the exertion of considerable force, the operator can use powerby simply depressing the lever B,

which, by means of the connection heretofore described, draws down thestrap S, and there by performs the operation by power, and therebylightens the work of the operator 'to a large extent.

It will be observed that the lever U, with its actuating foot-lever,forms at all times, whether the coil is larger or smaller, arelia-blemeans IIS for firmly pressing down the free end of the 7 last hoop, forthe purpose of securing it by a nail or nails. By curving the rail \V atits higher end a much larger impetus is gained than with a straightinclined rail for rolling away the coil.

The polished brass plate 0 is a great help to the operator, especiallywith dim light, to readily distinguish the spot, while the coilingheadis revolving, where to insert his first hoop; and this device permits ofrunning the coiler-head at a higher rate of speed.

The arrangement of the crossbar F at about midway between the bearingsof the sliding rods G has several advantages, of which. I will simplymention the following: Itdistributes the weight equally, leaves the rearend of the :BEST AVAILABLE COP machine unobstructed to run a belt fromany direction to the drive-pulley N, and it moves the ram with littlefriction and lost mot-ion.

\Vhat I claim as my invention is 1. The combination, with the frame A.and the coiling-head, of the curved rail \V, secured to said framebeneath the coiling-head, the footlever V, pivoted to said curved rail,the curved lever U, pivoted to the frame and terminating in a finger,and a rod connecting said lever V directly with the lever U,substantially as shown and described.

2. In a hoop-coiling machine, in combination with-the tension-strap andthe face-plate B, the guide-flange Q, secured near the outer edge ofsaid face-plate, and having the overhanging flange Q, all arranged tokeep the tension-strap from being displaced in remov ing the coil,substantially as described.

3. In a hoop-coiling machine, the combination, with the ram E, of across-bar, F, secured to its rear side transversely the frame andcarrying said ram, and of the sliding bolts G, adj ustabl y secured inhearings to the end of said cross-bar and having bear-in gs i uponopposite sides of said cross-bar, and a gate, K,.hinged at one end toone of said bolts, substantially as described.
